ToaZZ w/Lom t may concern.' Be it known thatI, ALBERT. GRIEVES, a

citizen of the United States, `residing at Springfield, in the countylof Clark and,

State of Ohio, have invented certain new and useful Improvements inMOwing-Machines, of which the following is a specification. I r

My invention relates to mowing machines wherein means are providedwhereby the nger bar maybe raised to substantially a verticalpositionrby means controlled by the operator, said means being connectedwith clutch shipping means forming` part of the power transmittingmechanism' and opera- Itively. connected with the cutting apparatus inal mannen to automatically disengage the clutch mechanism 'when thelinger bar has reached a predetermined angle of elevation, and to permitthe irengagement of the clutch mechanism when said bar has been loweredto a predetermined angle relative to the wheeled frame 'of the machine;the object of my invention being to provide an improved form of safetydevice operative in a manner to prevent thev engagement of the clutchmechanism until the linger bar has been lowered to a predetermined anglewith the wheeled frame of themachine and the Acoupling frame to anoperative position. I attain this object |by means of mechanism, oneembodiment of which is illustrated in the. accompanying drawings, in'which- Figure 1 represents a side elevation of part of a mowing machinehaving my invention forming a part thereof;"`

'F ig. 2 is a front elevation of part of the mechanism shown in Fig. 1,designed to illustrate the operation of tlie r aising and loweringmechanism connected with the cutting apparatus; f

The same reference .numerals designate like partsthroughout the severalviews.

1" 'r epresents the wheeled frame of the machine, having a driving'axleQ`journaled therein; 3 one of the carrying wheels upon said axle; 4adraft tongue y 5 a gear Wheel secured to said aXle and meshing with apinion 6 secured to the stubbleward end of a countershaft 7, having agear wheel 8 loosely mounted upon the opposite end thereof and meshingwith a pinion 9 secured to the rear end of crank shaft 10, that may beoperatively connected with the cutting apparatus in any well-known way.11 represents a clutch mechanism mounted upon the shaft 7 and adapted tocause the gear Wheel 8 to rotate with the shaft or remain idle,depending upon the position of adjustment of the clutch shippingmechanism. The clutch shipping mechanism iii- `cludes a Sleeve member1-2 suitably mounted upon the shaft 7 and provided with an arm 14 whichis connected, by means of a link 15, with a crank'arm 16 formed upon thestubbleward end ofl a. transverse rock shaft 17, the link having aslotted opening that receives a connecting pin in a manner permitting alimited rocking movement of the shaft independent of the arm 14,v therock shaft being jOurna-led upon V the wheeled frame ofthe machine andOperative, when rocked iii one direction, to disengage the clutchmechanism, and when Vrocked inan opposite direction to .permit saidmechanism to engage in any ofthe well-known ways. 18 represents an armsecured to the opposite end of said 'rock shaft, and 19 a linkconnecting said arm with a lifting lever 20 pivotally moimted upon thewheeled frame. 2l represents a coupling bar having its stublbleward endpivotally connected with the wheeled frame in a manner permitting theopposite end thereof to rise and fall relative to the wheeled frame. 22represents a coupling yoke provided with a sleeve portionV 23 thatreceives the coupling bar in a manner permitting the yoke to rockthereon, a head portion 24 having depending arms 25 at opposite endsthereof that are provided with openings adapted to receive hinge pins 2Garranged in the direction of the lineof draft of the machine, andwhereby an inner shoe 27 is connected therewith. 28 represents a linger'bar having the inner end thereof secured to said shoe, and 29 anupstanding Iarm secured to the rear end of the shoe. 30 represents'atransversely disposed lever pivota'lly connected intermediate its endswith a fixed part of the coupling frame and having a sheave 31 journaledupon a cross pin 32 at one end thereof, and 33 is a chain having one endadjustably connected, by means of an eye :bolt 34, with an arm 35forming part of the lifting lever 20, the chain engaging with thesheave'and having the opposite end thereof connected with the end of arm29 and operative in a manner to 'raise the coupling frame and swing vtheinger bar about the axis thereof froma horizontal to substantially avertical position when ,the lifting lever is swung rearward to the limitof its range of movement. 36 represents a foot lever having its forwardend pivotally connected ,with a rearwardly extending arm forming part ofthe hand lever, and 37 represents a latch member having its lower endpivotally connected with a bracket member 38 secured to the wheeledframe, t-he upper end thereof being provided with a hook portion 39adapted to engage with the hand and foot levers in a manner to retainthe coupling bar and finger bar in an elevated position, the latch beingnormally pressed in a direction to engage with the levers by means of acompression spring 40 operative between the wheeled frame and the latch.The hooked end of the latch is provided with an inclined surface 41 withwhich the levers engage in a manner to swing the latch laterally andpermit the levers to pass below the hook portion, and 42 represents alaterally extending wing portion whereby the operator may release thelatch by applying pressure to the wing.

The parts so far enumerated and described are common in the class ofmachines indicated, the novelty of my invention being the means providedwhereby the clutch mechanism, when disengaged by means of the connectionthereof with the lifting lever, will not be permitted to rengage untilthe finger bar and Vcoupling bar have passed through a predeterminedpart Vof their downward movement toward an operative position, the meansemployed being as follows: The lever 30 is provided with an arm 43 thatextends stubbleward from the axis thereof, and 44 represents a togglelink having its lower end pivotally connected with said arm and theopposite end thereof curved rearwardly and, by means of a pin 45,pivotally connected with the upperend of a swinging toggle arm 46, thelower end of said arm being pivotally connected with a xed part of thewheeled frame. The pin 45 is provided with a laterally projecting headportion 47 that is arranged within the path of a hook-shaped arm 48integral with the lifting lever and adapted to engage with the head ofthe pin when the lever is moved rearward for the purpose of `raising thefinger bar to a vertical position in a manner to swing the upper end ofthe link 44 rearward and downward to a position having the axis of thepin below a line drawn through the axis of the pivotal connection oflink 44 with arm 43 and the axis of the swinging arm 46, whereby theparts of the toggle mechanism are automatically locked against a returnmovement until the arm V46 is turned about its axis in a forward direction sufficient to throw `the axis of the pin 45 above such line. Whenthe lifting lever is in the position shown by dotted lines in Fig. 4 thecoupling bar has reached the limit ofits elevation, the finger bar hasbeen thrown tosubstantially a vertical position and the clutch mechanismis dis`` engaged. Vhen it is desired to lower the coupling bar and'allow the linger b'ar to swing to an operative position upon the ground,the hand lever is moved forward to a position shown in dotted lines inFig. 6, permitting the linger bar to swing outward and downward as thechain 33 is drawn under the sheave 31, the coupling bar remaining in anelevated position by reason of the fixed connection therewith of thelink 44 until a predetermined limit of forward movement of the handlever 'has been reached, and in which position a laterally projectingrib 49, integral with the hand lever, will engage with the pin 45 in amanner to swing the arm -46 upward and forward about the axisthereofuntil the axis of the pin has reached a position permitting thecoupling bar to fall to an operative position and simultaneously theengagement of the clutch mechanism.

Vhile I have in this application specilically described one embodimentwhich my 4invention may assume, it is to be understood that this form ofthe 'same is used only for purposes of illustration and that theinvention itself may be modified and embodied in other forms withoutdeparting 'from its Y spirit, it being my intention to include with- Ymined position.
